TURBINE WATER-WHEEL.

SPECIFICATION forming part of Letters Patent No. 231,079, dated August10, 1880.

Application filed November 10, 1879.

To all whom it may concern Be it known that we, ALBERT L. MOORE andNORMAN S. PARKER, of Portland, Multnomah county, State of Oregon, haveinvented a new and useful Improvement in Water- Wheels, of which thefollowing is a specification.

Our present invention is an improvement upon the water-wheel for whichLetters Patent were granted to us January 17, 1871; and the object ofour improvements is to obtain both percussive and reactionary effect bythe water upon the wheel; and, further, to construct the gate so that itmay be more easily operated than rim-gates as heretofore made.

Our invention consists in a wheel having inlet-chutes arrangedtangential to the outer circle of the wheel, and buckets formed withtheir back faces next to the chutes and at the inner ends with reverseangles or at right angles to the direction of the water, and at thefront with a bulge that narrows the waterspace between the buckets, sothat the water first strikes the buckets at right angles, and isdischarged at right angles to the inlet.

Figure l is a central vertical section of a water-wheel constructed inaccordance with our invention. Fig. 2 is a vertical plan view of thesame on line ac a; of Fig. 1.

Similar letters of reference indicate corre sponding parts.

The wheel consists of buckets a, sustained between the top plate, I),and bottom ring, 0, upon the spindle d, which rests on the step 0,. andis sustained above the wheel by the fixed bearing f.

The casing consists of a top plate, g, and flanged bottom ring, h,between which are sustained the partitions z, forming the inletchutesaround the wheel. From the top plate, g, and around the spindle d is asleeve, k, that sustains the bearing f.

The gate 1 is made as a ring that sets around the outside of the case,and when closed rests on the bottom ring, h.

Around the sleeve his a loose collar or sleeve, m, formed at its upperend with a flange, m, as shown, or with a series of legs or projectionsin place of the flange, from which rods 12 extend to lugs Z, which areformed at the upper edge of the gate. These rods are socured at theirends by nuts, so that the gate l and collar m are connected togetherfirmly.

Upon the top plate, 9, of the caseis a standard, 0, hung in lugs 0, sothat it may swing on its connection, and to the upper end of 0 is hung alever, 19, that is forked or formed with an eye, through which thecollar m passes, the collar m being hung to the lever by pins or screws19. By this construction the lever 12 is adapted for use in raising thegate, and the standard 0 becomes a movable fulcrum for the lever 19.

The partitions i, forming the inlet-chutes, are set at a tangent to thecircle described by the outer edges of the buckets, the direction ofeach partition being about at right angles to a radial line fromitsinner point to the center of the wheel.

The buckets a are formed on the back face, against which the waterstrikes with reverse angles-that is, from the outer edge the portion 1extends inward on a radial line, or about at right angles to theadjoining partitions 2', the portion 2 extends back of the radial lineat an obtuse angle to 1, and the inner point is formed by the bevel 3,which extends forward at an obtuse angle to 2. The outor end of eachbucket is formed straight in a line' which is the continuation of thepartitions i. The face of the bucket is curved forward to form a bulgethat narrows down the space between the buckets and curved back to forma point with the line 3 at the inner end.

The buckets are made long enough to permit their inner end to projectbeyond the inner periphery of the bottom ring, 0, so that these endsproject over the water-oulet.

scribed whereby the water has three actions 10 on the buckets-thestroke, reaction and suction.

Having thus fully described our invention, we claim as new and desire tosecure by Letters Patent- In a water-wheel the buckets havingapor- 5tion, 1, extended inwardly on a radial line at I right angles topartition 6, the portion 2 ex ALBERT L. MOORE. NORMAN S. PARKER.
